Whitespace, or WiFi-over-FM, is still dragging along. The problem is that the frequencies (TV bands) are available, but the thought of adding ANOTHER wireless transmitter to phones, laptops, and other devices is stalling development.

I would love to see it happen, or something similar, because of the dead areas that still exist around the US and Canada. As a sometimes storm chaser, there's nothing worse than chasing a mesocyclone and then hit a dead area and lose your live radar!
